In sync.rb what are Sync::UN, Sync::EX and Sync::SH all about? Thanks, T.

Oh, one other thing. SyncEnumerator has nothing to do with Sync right? Maybe it would be better if were named something else (TandemEnumerator come to mind). Thanks, T.

SH is shared: many threads may hold the lock as long as they all requested a shared lock. The intent is to allow either multiple readers or a single writer (but not both) inside the critical section(s) of code.

No one know? I assume Sync::EX when underlying data is gogin to change and Sync::SH when it's not? Can EX just be used alwasy instead? T.
